Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hazardous waste treatment equipment and relates to a multi-stage condensation device. Background Art
[0002] During the treatment of hazardous waste, distillation separation using the difference in boiling points of substances is a common method. A condenser is a device for cooling a certain vaporized substance below its boiling point for the recovery of the substance. Common condensers generally use a set of condensation tubes to intercept waste gas, and the flow efficiency of the waste gas flowing naturally is relatively low, and it is difficult to control the cooling temperature during the residence time of the waste gas. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a multi-stage condensation device for the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the condensation efficiency.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A multi-stage condensation device, characterized in that it includes a ventilation box, the ventilation box includes a cylindrical shell and an air inlet box connected to the inner cavity of the shell. The width of the air inlet end of the air inlet box is greater than that of the air outlet end. The air outlet end of the air inlet box is connected to the ventilation box. A impeller is rotatably connected in the ventilation box. The ventilation box is provided with air outlet holes along the axis direction of the impeller. A plurality of groups of condensation tubes are arranged at intervals in the air inlet box. The impeller is driven by a driving motor; an annular liquid discharge hole is arranged outside the air outlet hole, and the liquid discharge hole is located outside the impeller.
[0005] Further, multiple groups of condenser tubes are connected in parallel.
[0006] The waste gas enters the shell from the air inlet box. The air inlet box has a gradually narrowing structure, which makes the air flow velocity gradually increase. The impeller rotates to suck in the waste gas and discharge it from the air outlet holes. The rotation speed of the impeller can be controlled to adjust the waste gas flow rate, thereby effectively controlling the condensation temperature; in addition, the impeller sucks away both the liquid and the gas. Under the action of the centrifugal force of the impeller, the liquid is thrown outward to the liquid discharge hole, while the gas is discharged from the air outlet holes. This forced control method of gas flow has high efficiency and high gas-liquid separation efficiency. Brief Description of the Drawings

[0011] The following are specific embodiments of the present utility model, and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0012] As Figures 1 to 3 shown in the multi-stage condensation device, which includes a ventilation box. The ventilation box includes a cylindrical housing 1 and an intake box 2 connected to the inner cavity of the housing 1. The intake end width of the intake box 2 is greater than the outlet end. The outlet end of the intake box 2 is connected to the ventilation box. A impeller 3 is rotatably connected in the ventilation box. An air outlet hole 4 is opened in the ventilation box along the axis direction of the impeller 3. A number of groups of condensation tubes 5 are arranged at intervals in the intake box 2. The impeller 3 is driven by a driving motor; an annular liquid discharge hole 6 is provided outside the air outlet hole 6. The liquid discharge hole 6 is located outside the impeller 3. Multiple groups of condenser tubes are connected in parallel.
[0013] The waste gas enters the housing 1 from the intake box 2. The intake box 2 has a gradually narrowing structure, so that the air flow velocity gradually increases. The impeller 3 rotates to suck in the waste gas and discharge it from the air outlet hole 4. The rotation speed of the impeller 3 can be controlled to adjust the waste gas flow rate, thereby effectively controlling the condensation temperature; in addition, the impeller 3 sucks away both the liquid and the gas. Under the centrifugal force of the impeller 3, the liquid is thrown outwards to the liquid discharge hole 6, while the gas is discharged from the air outlet hole 4. This forced control method of gas flow has high efficiency, and the gas-liquid separation efficiency is also high.
